In this tutorial, we'll guide you through interfacing an Arduino with an ultrasonic sensor to measure distance and show it on the Serial monitor. We'll start by explaining how to interface the ...

The use of wireless communication protocols (e.g., Bluetooth, Wi-Fi, LoRa, Zigbee) to connect Arduino boards with sensors. This enables remote data acquisition and control in applications such as ...

So in today's project, we will learn all about flex sensors, how it works, and how you can interface them with an Arduino. The flex sensor, also sometimes called as bend sensor, has two pins, one is ...

The microcontroller-based concept was chosen because I wanted to scale the sensor system later to suit other applications. Here is the diagram of my Arduino infrared close proximity sensor. As you can ...

Can be extended to more than two doors. Since OpenGarage only supports one door per install and I had trouble with ESPHome to work with my two sensors consistently, I decided to create my own. The ...

Earlier this year, Seeed Studio introduced the Grove Beginner Kit for Arduino that included the Arduino UNO compatible Seeduino Lotus board placed at the center and ten pre-wired and detachable Grove ...

The hardware is consists of an Arduino microcontroller (here an Arduino Uno R3) and a pre-wired soil moisture sensor module. The soil moisture sensor module , built around the LM393 comparator, gives ...

Automating household or office systems can be achieved using an Arduino Nano, a passive infrared (PIR) motion sensor, and a relay. The primary aim is to create a control system that activates or ...

Arduino has made all their hardware open source, meaning that these little gizmos are everywhere. That makes it a cost-effective way to build whatever you need, from switches to sensors. There are ...
